Second installment of the James Debug series. This time, James has fallen through a crack in time and must find a way to come back to the present. The manual says (translated from French):

"What an awful waking up!

James Debug suddenly understands why he ended up in this primitive cave: he must have slipped through a crack in space and time while asleep. The only way of going back to the present his fevered mind can come up with is to try and gather the modern items scattered around the cave, in order to reopen the crack in time."
